The aerobic activity that has the highest impact on the joints among the options provided is:
C. running
Running is a high-impact activity because each time your foot strikes the ground, it creates a force that is several times your body weight, impacting the joints, especially the knees and hips. This repetitive impact can put stress on the joints over time, potentially leading to injuries like shin splints, stress fractures, or joint pain.
In comparison:
A. Cycling is a low-impact activity as it is gentler on the joints since your body weight is supported by the bike seat, reducing the stress on joints.
B. Swimming is a non-weight bearing activity that is very low impact on the joints as the water supports your body weight, making it a great option for individuals with joint issues.
D. Walking is a low-impact activity that is generally easier on the joints compared to running due to less force being exerted on the joints with each step.
